How to restore Cpanel to DNS Zone link

I am new to WHM/Cpanel and are just setting up a new dedicated server. I am totally new to Linux systems - having managed many Windows 2000 servers before. I have gone thru the WHM/Cpanel Documentation which is quite helpful in terms of a reference or index of what each function does. Is there a guide that is more step-by-step or sequential in terms of how to set up reseller accounts and domains etc. ?
